INTRODUCTION

SierraSil® is a unique mineral complex sourced from a pristine deposit located high on the
eastern slopes of the US Sierra Mountains. It was first discovered by a gold prospector over
thirty years ago who found something more valuable than gold – the natural gift of health. He
observed wildlife grazing on a particular deposit and then tried the mineral on his domestic
animals. Long story short, people who tried it often reported spectacular results.

Our business was founded in 2003 to commercialize this very special mineral deposit and our
simple goal is to help people become healthier and more active.

We strive to be ethical; to treat all people fairly and with respect; and to stand behind our
products with operating standards that meet or exceed regulatory requirements. Additionally,
verifying safety and supporting health claims with quality first hand research has been very
important to us, as is a hassle free consumer satisfaction guarantee. This Professional Refer-
ence Guide highlights that research and provides additional supporting documentation.

SierraSil® is the trade name for a unique mineral complex sourced from a mineral deposit
located high on the eastern slopes of the US Sierra Mountains.

Dr. Hayden Murray, Professor Emeritus, Economic Geology, Clays, and Industrial Minerals,
Indiana University, an expert in clay and related mineralogy, describes the deposit as an
alteration of a volcanic tuffaceous rock as a result of warm acid fluids which came from
significant depths to the surface along fractures in the parent tuffaceous rock millions of
years ago. “These hydrothermal fluids have altered the feldspar and zeolite minerals to
montmorillonite (an absorbent clay), jarosite (a potassium iron sulphate) and hematite (an
iron oxide). In addition to the above minerals, quartz (a pure silicon dioxide) and some
partially altered feldspars are present as well.”

Dr. Murray, who has studied deposits all over the world, said after conducting an X-Ray
diffraction analysis “In my more than 50 years of mineral research, I have never seen a
combination of minerals like this before”.

This mineral structure contains approximately 40 identifiable macro and trace mineral
elements. However due to the tightly bound silicate mineral structure, only a portion of the
minerals are available to the body. The available minerals per 2 gram serving are (approximate
mg): Calcium 23, potassium 20, sodium 12, aluminum 6, phosphorus 3, magnesium 2, iron
1, silicon 1 and the following between 1 mg and 0.01 mg: manganese, barium, copper, cobalt,
and zinc.

Much of the mineral content is non-soluble except at very low or high pH levels outside the
pH range in the human stomach. However, the SierraSil® mineral structure will bind a
variety of compounds by either absorbing or adsorbing them (collecting in a thin layer) to its
molecular surface. This characteristic supports the detoxifying properties of SierraSil® and
why it is NOT recommended to be taken with medications.

RECOMMENDED DOSE: (ADULTS) Take 3 capsules once daily with water on an empty stomach.
Persons with larger bodies or BMI of over 25 should consider taking 4 or 5 capsules per day, or
a larger scoop of the powder.

DIRECTIONS FOR USE: For best results, take SierraSil® Joint Formula14™ (JF14) with water at least
one hour before or after a meal or other beverages such as coffee, pop, tea, juice or milk. Take
critical medications four hours before or after JF14. JF14 has detoxifying properties due to its
clay-like silicate mineral structure, and it is strongly recommended to drink plenty of water for
best results with SierraSil®. Increased water intake assists the body in flushing out toxins and
heavy metals that are eliminated by the body when using SierraSil®.

For those in weakened conditions, living with multiple pre-existing medical conditions or
sensitive stomachs, start with one capsule, once per day and gradually work up to the
recommended dose.

For those without sensitive stomachs, if results do not manifest within the first 7 days consider
taking a loading dose. A loading dose is double the recommended daily dose for 7 days and can
be taken to help increase results.

CAUTIONS AND WARNINGS

CAUTIONS: For a very small percentage of SierraSil® users, the detoxification process can
cause some transient discomfort at first, known as a healing reaction, while the body adjusts to
SierraSil® Joint Formula14™. A healing reaction is a temporary process that the body endures
as it moves towards optimal balance and function (homeostasis). Symptoms of healing
reactions vary, and may include headache, changes in bowel movements or a slight stiffening
of the joints. These reactions are temporary and normally subside within 1 to 7 days of using
SierraSil® Joint Formula14™. If the symptoms are too uncomfortable, lower the dose to 1
capsule or 667 mg daily and gradually increase to the recommended dose. To facilitate the
detoxification process, it is critical to consume plenty of water (6+ glasses daily) while taking
SierraSil® Joint Formula14™ to assist the body with eliminating toxins. Increased water intake
will also reduce the risk of constipation while taking SierraSil.

WARNINGS: Pregnant or nursing women and persons with known medical conditions (such
as cardiovascular diseases) should consult with their health care practitioner prior to using
SierraSil® Joint Formula14™. SierraSil® Joint Formula14™ should be kept out of reach of
children. SierraSil® has not been clinically tested for these population groups.

Professional Reference Guide Cautions and Warnings 7
CONTRAINDICATIONS: SierraSil® Joint Formula14™ should not be taken at the same time of day as
critical medications. The absorptive mineral complex in SierraSil® Joint Formula14™ may bind
with medications due to its highly absorptive and adsorptive properties.

CLINICAL SUPPORT
Study Abstracts for SierraSil®
SierraSil has made and continues to make a significant investment in research to demonstrate
both the safety and efficacy of the SierraSil® ingredient. These studies are summarized as follows:

1. Human pilot study

TITLE: A pilot study to test the safety and efficacy of the mineral supplement SierraSil® in
osteoarthritis of the knee.

OBJECTIVE: A pilot study to evaluate the safety and efficacy of SierraSil® in patients suffering
from osteoarthritis of the knee. The 2003 study was conducted in a randomized fashion to
administer patients diagnosed with moderate osteoarthritis of the knee with SierraSil® alone or
SierraSil® plus a proprietary cat’s claw herbal extract.

METHODS: Baseline WOMAC scores were established after which the patients received one
capsule three times daily of the treatment for 10 days. Post-treatment WOMAC scores and side
effects were also recorded. The parameters of the study included WOMAC scores, OA clinical
symptoms, stair climb ability, pain and stiffness reduction and quality of life.

RESULTS: 100% of the subjects reported a significant improvement within one week of
treatment on either SierraSil® alone or SierraSil® with the cat’s claw, with no concomitant
medications (i.e. aspirin, acetaminophen) required or side effects reported.

CONCLUSION: This pilot study showed that SierraSil® alone or in combination with cat’s
claw provided patients (with previously diagnosed osteoarthritis) benefits that were clinically
measurable. This pilot study therefore warranted further investigation to determine the
biological mechanism of action, the appropriate dosage and SierraSil®’s safety and efficacy
in a larger scale clinical trial.

2. Double blind, placebo controlled, OA study

TITLE: Early relief of osteoarthritis symptoms with a natural mineral supplement and a
herbo-mineral combination: A randomized controlled trial [ISRCTN38432711]

OBJECTIVE: This study was designed to determine if a natural mineral supplement, SierraSil®,
alone and/or in combination with a cat’s claw herbal extract (Uncaria guianensis), Vincaria®,
has therapeutic potential in mild to moderate osteoarthritis of the knee.

METHODS: 107 patients with mild to moderate osteoarthritis of the knee were randomly

RESULTS: SierraSil® was able to produce significant improvement in WOMAC and VAS scores
after 8 weeks (P < 0.001) either alone or in combination with Vincaria®. SierraSil® groups
also produced a faster onset of benefits (at week 1, 2, and 4) in reference to baseline values
when compared to placebo group. At 4 weeks, all the SierraSil groups displayed a 38–43%
WOMAC improvement.

CONCLUSION: SierraSil® alone and in combination with cat’s claw extract improved joint health
and function within 1–2 weeks of treatment. SierraSil® may offer an alternative therapy in
subjects with joint pain and dysfunction. See PMID: 16242032 PMCID: PMC1276811 for the
peer reviewed, published paper. Journal of Inflammation. J Inflamm (Lond). 2005;2:11.

3. Double blind, placebo controlled, cross-over, OA study

TITLE: A randomized, double blind, placebo controlled cross over study to explore the efficacy
and safety of SierraSil® Joint Formula14™ in adults with osteoarthritis of the knee.

OBJECTIVE: The primary objective of this study was to assess the efficacy of SierraSil® at 2 g/
day on the symptoms of osteoarthritis as assessed by WOMAC™ Pain subscale in Canadian
subjects with osteoarthritis of the knee. Secondary objectives of the study were to determine
changes in WOMAC™ osteoarthritis index physical function and stiffness subscales, SF-36
questionnaire scores, inflammatory markers such as hsCRP, TNF, and IL-6, onset of analgesia,
amount of rescue medication used, safety parameters including vital signs, adverse events, and
laboratory tests.

METHODS: In this randomized, double-blind, placebo controlled, cross over study, a total of 230
subjects were screened and 150 were found to be eligible to participate in the study. 75 subjects
went on the SierraSil® treatment and the other 75 on placebo. Of the 150 subjects 25% were of
healthy weight while 75% were large or obese by BMI measurement.

RESULTS: Subjects with a WOMAC™ Pain score between 16 and 33.3 mm at baseline showed
a decreasing trend in Pain score from baseline to week 4. During the washout period, these
subjects’ Pain scores increased suggesting efficacy of SierraSil®. Though subjects on placebo
had an initial decrease in Pain score from baseline to week 2, an increase was seen by week 4.
Subjects with a WOMAC™ Pain score between 66.7 and 100 mm at baseline showed a
decreasing trend in Pain score from baseline to week 2 and plateaued by week 4 for both
Placebo and SierraSil®. Within groups, subjects on SierraSil® demonstrated statistically
significant improvements in SF-36 scores from baseline to week 4 for the domains: Physical
Function, Role Limitation due to Physical Health, Vitality/Energy, Social Functioning, and
Bodily Pain. Furthermore, subjects on SierraSil® showed statistically significant improvements
in Total SF-36 scores, Total Physical Activity and Total Mental Health.

Professional Reference Guide Clinical Support 9
CONCLUSION: The study found that SierraSil® was effective in relieving pain associated with
osteoarthritis as indicated by both WOMAC scores and SF-36 scores. SierraSil® was found in
this study to be effective in temporary relief of joint pain, with more profound effect in subjects
with normal body weight (BMI < 25.00 Kg/m2), suggesting that larger bodies would benefit
from a larger dose than 2 g/day. This study was published in the following Dove Press Journal:
Open Access Rheumatology: Research and Reviews 3, Oct 2014.

OBJECTIVE: The purpose of this study was to examine whether Sierrasil® could improve anaer-
obic power in a group of well-trained athletes. A secondary purpose was to examine the effect
of Sierrasil® on the severity of delayed onset muscle soreness (DOMS).

METHODS: 10 male, varsity football players were studied in a double-blind, cross-over design.
The athletes (mean age= 22 years; height= 183.6 cm; weight = 90.3 kg) performed three
Wingate cycle ergometer tests 5 minutes apart as a test of peak power, average power and
fatigue index. They recorded DOMS on a 0-10 visual analogue scale (VAS) at 24, 48 and 72
hours post-exercise. Prior to exercise and 5 minutes following the last Wingate test, blood was
taken for analysis of selected cytokines. The athletes were randomly assigned to Sierrasil® or
placebo groups for three weeks and, following a three-week washout period, the experimen-
tal treatments were reversed. The products were dispensed according to the manufacturer’s
recommendation.

RESULTS: All athletes completed the trial. Sierrasil® was well tolerated by highly trained male
athletes. There were no adverse effects reported. Following Sierrasil® supplementation the
peak power increased by 33.8 W (a 3% increase) and mean power by 6.7 W (a 1% increase). In
the placebo group the peak power decreased by 11.2 W (-2.6%) and the mean power decreased
by 17.2 W (-1%). DOMS values on the VAS were higher in the placebo group at 24, 48 and 72
hrs post-exercise (P= 3.2, 2.2, 1.3 vs. Sierrasil®= 2.5, 1.6, 0.6). There were no statistically
significant changes in the performance measures between the two groups however (p>0.05).
There were no significant changes in the cytokine measures following supplementation with
either Sierrasil® or placebo.

CONCLUSION: The results showed that Sierrasil® is safe to use in highly trained athletes and
resulted in improvements in anaerobic power and in reducing the level of DOMS post-exercise
that the researchers, Dr. Don McKenzie and Dr. Jack Taunton describe as “sport significant”.

OBJECTIVE: A pilot study led by Dr. James Lavalle designed to assess potential for accumulation
of toxic minerals in humans and to reveal if SierraSil® has a chelating effect on toxic metal
accumulation.

METHODS: 12 subjects entered the study designed to examine the effects of SierraSil® on 16
potentially toxic metals and 19 essential elements over a 6-month period.

RESULTS: 7 subjects completed the study. The data reveals that arsenic levels appear to rise from
T0 to T3 (and from T0 to T6). However, they declined from T3 to T6, although this change was
not statistically significant. All the measurements for arsenic levels remained within the nor-
mal reference range. If the arsenic in SierraSil® was bioaccessible, then the levels should have
continued to rise. As a natural chelating agent, ingestion of SierraSil® caused a 56.9% decrease
in lead between T0 and T6, and a 62.7% decrease between T3 and T6, both of which were sta-
tistically significant at the 5% level.

CONCLUSION: It appears that daily ingestion of SierraSil® at 4 g/day may have a profound effect
on the lowering of lead levels and may have the potential to lower the risk of the adverse health
effects associated with lead exposure.

OBJECTIVE: This laboratory analysis was conducted to examine the blood chemistry and other
health indicators of patients who have been taking SierraSil® over a long period of time
(2 to 5 years).

METHODS: A full laboratory analysis was conducted on 9 patients with a mean age of 60.1
years with the range of 41–85 years old. The average use of SierraSil® in this study was 2–4
capsules per day for a minimum of 2 years. Haematology, general blood chemistry, adrenal
function and serum proteins were included in the laboratory analysis.

RESULTS: Lab analysis showed that these patients have normal to low-normal profiles of
parameters described above, for instance, the cortisol is averaging 350.38 nmol/L when the
normal range is 140 – 690 nmol/L, showing that adrenal function of the 9 patients was healthy.
A more important and more relevant testing was the C - reactive protein (CRP) as it relates to
inflammatory processes in the body. The average CRP level of the 9 patients was
2.2 mg/L where the normal range is < 5.0 mg/L. this again shows that SierraSil® may have
anti- inflammatory properties in patients suffering from osteoarthritis; however OA markers
were not included in this lab analysis.

Professional Reference Guide Clinical Support 11
CONCLUSION: Patients who are on long term use of SierraSil® were found to have a healthy and
normal biochemistry profile when compared to the established normal ranges.

OBJECTIVE: Thisstudy investigated the hypothesis that the unique clay-based mineral
supplement SierraSil® alone, and in combination with an extract of cat’s claw, Vincaria®,
could limit human cartilage degradation-activated chondrocytes.

METHODS: The investigative model used was human cartilage tissue, obtained at the time
of knee surgery. SierraSil® was subjected to neutral, alkali, and acid washes, followed by
neutralization before addition to cartilage explants or cultured chondrocytes (0.05, 0.1, and
0.2 μg/ml). Vincaria®, an alkaloid depleted aqueous extract of cat’s claw (Uncaria Guianensis)
was studied in combination with SierraSil® (2.5, 5 and 10 ng/ml).

RESULTS: Chondrocytes were activated with the addition of the inflammatory cytokine interleu-
kin-1 (5 ng/ml). Measured outcomes were media nitrate/nitrite levels as an index
of nitric oxide production, and media glycosaminoglycan (GAG) concentrations as an index
of matrix breakdown. Following neutral or alkali washes, a small reduction in GAG release
was observed with neutral extracts (p<0.05). The combination of SierraSil® + Vincaria®
significantly reduced both GAG and nitric oxide release under these conditions. Following an
acid wash to mimic passage of the material through the stomach, SierraSil® alone significantly
reduced IL-1-induced GAG release by 68–73% (p<0.01) and SierraSil® + Vincaria® by 58–77%
(p<0.01). Production of NO by human chondrocytes was also reduced by acid-washed SierraSil®
alone (p<0.05) and was more pronounced with the SierraSil® + Vincaria® combination (p<0.01).
IL-1-induced nitric oxide production and GAG release is known to reflect the activation of
inducible pathways (inducible nitric oxide synthase and matrix metalloproteases).

CONCLUSION: The attenuation of these events suggests that SierraSil alone or in this herbo-min-
eral combination limits cartilage destruction by curtailing these transcriptional events in
chondrocytes. Results suggest that this nutraceutical-based therapeutic agent may offer a new
approach to limiting joint destruction and immobility associated with arthritis.

Published in The Journal of the American Nutraceutical Association. Volume 7, No. 2, 2004

METHODS: The powder was stored at room temperature during the study. A large portion of it
was insoluble in common solvents that were compatible with the assay. The insoluble material
precipitated in the testing agar plates and interfered with colony counting. In the main studies,
the sample was prepared in DMSO and water by shaking at 45oC for two days. Exposure
concentrations were expressed in “mg eq. per plate”. “Mg eq.” represented the number of
mg from which the extract was prepared. DMSO extracted SierraSil® was tested in a plate
incorporation assay; water extract, in pre-incubation assay.

RESULTS: Bacterial toxicity was observed in all strains exposed to DMSO extracts with S9.
This limited the maximum exposure concentrations to 2.07 mg eq. per plate for this part of the
study. With the addition of S9, exposure to as high as 56.00 mg eq. per plate of DMSO extract
did not cause obvious toxicity. Water extract was largely non-toxic with or without S9.
Maximum extractable concentration was in this case included in the exposure concentrations
that ranged from 0.55 to 44.40 mg eq. per plate. All tester strains showed only background
level of reversion at any exposure concentration with either extract. The observed means for
triplicate plates of each concentration was largely within the range of the means ± 2 SD of the
corresponding solvent controls.

CONCLUSION: It was concluded that the mineral was not mutagenic to S. typhimurium strains
TA-98, TA-100, TA-1535, TA-1537 and E. coli strain WP2 uvrA under the test conditions.

9. Acute oral toxicity (AOT)

TITLE: Review of SierraSil® acute oral toxicity test.

ABSTRACT: The acute oral toxicity study completed on SierraSil® found that the acute oral LD50
of SierraSil® to be in excess of 2000.0 mg/Kg body weight. No effects of toxicity or mortality
were observed at any point during the 14 days of testing. The animals gained weight during
the test. Post-testing examination showed no gross pathological findings in any of the five rats.

Professional Reference Guide Clinical Support 13
OBJECTIVE: The study was to assess the toxicological profile of SierraSil® when rats are exposed
daily to the test article over a period of 90 days, by oral gavage.

METHODS: Groups of 10 male and 10 female Sprague Dawley rats were administered SierraSil®
by oral gavage daily at the doses of 100 mg, 550 mg or 1000 mg per kg body weight for 90 days
and were sacrificed on day 91 to evaluate its toxicity. Concurrent control group receiving vehicle
at 10 ml/kg was also maintained. Additionally, groups of 5 rats per sex receiving vehicle at 10
ml/kg and the test article at 1000 mg/kg levels were further observed for a period of 28 days
following 90 day exposure, for assessment of reversibility, persistence or delayed occurrence
of toxicity.

RESULTS: There was no treatment related mortality among rats exposed to SierraSil® at all three
doses. No findings indicative of neurotoxic potential of the treatment were reported. Body
weight gain by treatment group was found to be comparable to that by the control group. Food
consumption was also comparable between the treatment group and control group. Haema-
tology, clinical chemistry, urinalysis, organ weights, gross pathology and histopathology all
revealed no significant difference between treatment group and placebo group.

CONCLUSION: Based on the findings of this study, the no-observed-adverse-effect-level (NOAEL)
of SierraSil® in Sprague Dawley rats, following oral administration for 90 days was found to
be more than 1000 mg/kg body weight (equivalent to about 35 times the recommended
dosage/serving).

OBJECTIVE: The study was to address body weight and liver chemistry analysis of rats that had
been fed SierraSil® over a period of 90 days by oral gavage.

METHODS: In the same study as described previously, liver samples for rats treated with
SierraSil® were prepared and analyzed as it is a safe assumption that hepatic metal content
is reflective of levels in other tissues of the animal.

RESULTS: Total iron content of the liver, total lead content of the liver, total arsenic content of the
liver and total aluminum content of the liver were analyzed in 10 rats from the control group
and 10 rats from the high dose group (1000 mg/kg body weight of SierraSil®). The weight of
the liver was also compared between control and high dose groups. No statistically significant
difference was found in any of the above liver analyses.

CONCLUSION: Even at very high dosages there was no accumulation of metals tested in the liver,
even a trend to lower lead levels.

OBJECTIVE: Thisstudy was to investigate the effect of SierraSil® on [3H-Methyl] Thymidine
uptake as a measure of radiation absorption by various human cells.

METHODS: An in vitro assay was designed to measure the uptake of [3H-Methyl] Thymidine
by three human cell lines: human liver (THLE-2), human normal skin (NHEM) and human
melanoma skin cells (A375). SierraSil® powder dissolved in complete growth media
provided ~2.4% soluble solids in the filtrate that were used in the assay. [3H-Methyl] Thymidine
at concentrations of 0.5, 0.1 and 0.05 μCi were tested at 24, 48 and 72 hours after incubation
with the test product.

RESULTS: After 24 hours of incubation there was a significant decrease in the amount
of radiation detected in THLE-2 cells exposed to all three concentrations of [3H-Methyl]
Thymidine in the presence of SierraSil® compared to control liver cells. After 24 hours of
incubation there was a significant decrease in the amount of radiation detected in NHEM cells
exposed to 0.05 μCi of [3H-Methyl] Thymidine in the presence of SierraSil® compared to control
normal skin cells. After 72 hours of incubation, there was a significant decrease in the amount
of radiation detected in A375 cells exposed to 0.05 μCi of [3H-Methyl] Thymidine in the pres-
ence of SierraSil® compared to control melanoma cells.

CONCLUSION: Analysis of the data showed that cells cultured in the presence of SierraSil®
powder demonstrated lower incorporation of [3H-Methyl] Thymidine compared to cells
cultured in the absence of SierraSil®. The study also established that the absorption of
radiation in the form of [3H-Methyl] Thymidine is dose, time and cell type dependent.

13. Bio-accessibility testing

TITLE: Dissolution Testing of SierraSil® USP <711>

OBJECTIVE: This experiment is conducted to determine if metals from the SierraSil® product are
bioaccessible following digestion with simulated gastric and intestinal fluids at physiological
temperature (37°C).

METHODS: The test protocol follows the Dissolution method <711> described in USP 24 NF-19.
The experiment was conducted in a water bath at 37 ± 2°C. All materials were cleaned and
rinsed according to standard procedure. Both digestive solutions – gastric fluid and intestinal
fluid – were prepared according to the USP 24 NF-19 method. The bioaccessibility of metals in
the test sample was estimated using the equation: [concentration of a given metal determined
in the chime] / [concentration of the given metal determined in the SierraSil® sample before
digestion x 100%].

Professional Reference Guide Clinical Support 15
RESULTS: The mean concentration of mercury was 0.213 ± 0.004 μg/0.667g. However, the mean
bioaccessibility of mercury was 1.4%. The concentration of lead in the test sample was 4.3 ±
0.04 μg/0.667g, while the bioaccessibility was 0%. The bioaccessibility of cadmium was 108%,
however, the concentration of cadmium in the test sample, 0.03 ± 0.002 μg/0.667g, was very
close to the limit of detection (0.02 μg/0.667g).

CONCLUSION: The estimated daily intake for elements of potential concern, based on an
expected consumption of three 0.667g-capsules per day (containing a total of 2g of SierraSil®),
showed that the concentrations of mercury, lead and cadmium in the sample were extremely
low and came well within the limits of Health Canada regulations.

14. N of 1 Study

TITLE: N of 1 Study assessing soreness in a healthy adult male.

OBJECTIVE: Dr. James McCormack, UBC Title, offered to supervise a double blind, placebo
controlled, multiple cross over N of 1 Study to assess the efficacy of SierraSil JF14 in a healthy
SierrraSil customer, challenging placebo effects and speed of benefits.

METHODS: Eight bottles of a two week supply (4 each of placebo and treatment) were random-
ized on a double blind basis. The adult male patient kept a log of activity and noted soreness
on a scale of 1 to 7 with definitions for each as established by Dr. McCormack. For example 1,
represented no soreness to 7 which represented very severe soreness, cannot be ignored and
markedly limits daily activity and often requires rest.

RESULTS: The patient soreness scores ranged from 1 (no soreness) to 4 (moderate soreness -
cannot be ignored but does not influence my daily activities). The average soreness score (per
bottle/2 week blocks) on treatment was 1.29 and the average soreness score on placebo was
2.13, a difference of 0.84 (placebo soreness 65% higher than treatment). All treatment score
averages were lower than any of the placebo score averages. This is significant given the nature
of the study, with what turned out to be 5 transitions from either placebo to treatment or treat-
ment to placebo in the 16 week period, suggesting that the onset of benefits was rapid when on
treatment, but there was similarly short ‘tail’ to the benefits.

CONCLUSIONS: For the patient in this double blind, placebo controlled multiple cross-over study,
SierraSil JF14 significantly reduced soreness associated with activity such as running and other
exercise.

SierraSil® may also aid digestive health, reduce acid reflux and support faster recovery of
certain injuries such as rotator cuff and carpal tunnel. However, these are anecdotal
observations and have not yet been studied clinically.

SierraSil® is not recommended for people on numerous medications, as SierraSil®’s
detoxifying properties may partially absorb these medications. It is also not recommended for
pregnant or nursing women as it has not been clinically tested in this population.

HOW DOES SIERRASIL® JOINT FORMULA 14™ WORK?
We know from published in vitro research at Case Western Reserve University that SierraSil®
moderates inflammation and curtails cartilage breakdown. These results are consistent with
those of the human clinical studies. SierraSil® may also help to detoxify the body, an inference
that can be reasoned based on the studies completed.

WILL SIERRASIL® JOINT FORMULA 14™ HELP WITH ARTHRITIC SYMPTOMS?
Clinical and anecdotal evidence confirms that SierraSil® Joint Formula14™ is likely to provide
noticeable benefits for symptoms of arthritis within two weeks. SierraSil® Joint Formula14™
reduces inflammation, down-regulates specific enzymes involved in the inflammatory process
and reduces cartilage breakdown which are factors leading to the development of arthritic
symptoms. Human studies confirm these findings for osteoarthritis, showing that SierraSil®
Joint Formula14™ significantly improves joint health and function within a 2-week period. In
addition, many consumers report significantly reducing their use of pain medications such as
NSAIDs while using SierraSil®. SierraSil® was awarded United States patents in 2009 and in
2011 as a nutritional supplement for osteoarthritis.

CAN PATIENTS WITH SENSITIVE STOMACHS TAKE SIERRASIL® JOINT FORMULA 14™?
In case of sensitive stomach, patients should start with 1 capsule per day, gradually increasing
the number of capsules to the recommended dose over 14 days. People with GI conditions such
as acid reflux, gas, bloating, constipation, leaky gut syndrome, IBD, colitis, diverticulitis, IBS
and Crohn’s disease have been reporting benefits from taking SierraSil® Joint Formula14™. The
mineral structure of SierraSil® Joint Formula14™ has detoxifying properties that may
help to cleanse and promote a healthy digestive system and possibly protect the stomach lining.

WHY IS THERE AN IRON WARNING ON THE LABEL FOR SIERRASIL®
JOINT FORMULA 14™?
There is approximately 120 mg of total iron content per serving of SierraSil® Joint
Formula14™; however studies indicate that only about 1.2 mg of iron or approximately 7%
of the recommended daily iron intake is bioaccessible. There is a required warning on the
labels of all ingested products to protect against young children (under the age of 6)
accidentally consuming an entire bottle of iron-containing supplements and possibly
experiencing harmful side effects. SierraSil® Joint Formula14™ has been tested at up to 70
times the recommended dosage in accordance with standardized procedures and shown to
have no indications of toxicity.

IS THERE ALUMINUM IN SIERRASIL®?
Yes, there is. The bioaccessible amount is less than 10mg per daily dose. This is a
fraction of the aluminum content of commonly consumed products such as antacids, baked

goods and cheeses. Most of the aluminum in SierraSil® is tightly bound to the silicate fraction
that passes through the body with no chance for absorption. Furthermore there is evidence
that even at extended levels of 35 times the recommended SierraSil® dosage or serving that
there is no accumulation of aluminum. Aluminum is the third most abundant element on
earth and is part of most of what we eat.

HOW IS SIERRASIL® JOINT FORMULA 14™ DIFFERENT FROM OTHER NATURAL JOINT
HEALTH PRODUCTS?
Most natural health products provide ingredients that are building blocks of human cartilage
or joint structure. These include glucosamine, condroitin, fatty acids, hyaluronic acids,
collagen and so forth. In theory these products supplement the body’s natural regenerative
process. SierraSil® and some herbs are among the joint health ingredients that calm the
underlying inflammation. SierraSil® can be complimentary to other ingredients or products
but the collection of SierraSil® attributes make it stand out. These attributes include:

• SierraSil, when taken as directed, has very high efficacy rates – most patients will feel results.
• SierraSil usually provides reductions in aches or stiffness quickly. Often within a few days but guaranteed
within 14 days (or money back).
• SierraSil calms the underlying inflammation, giving the body a better chance to heal itself.
• SierraSil appears to assist peak power and reduce delayed onset muscle soreness.
• SierraSil may have additional benefits such as detoxifying.
• SierraSil is suitable for most dietary types, including diabetics, vegans and celiac sensitivities.
• SierraSil is mineral based, requiring no pesticides, fertilizers or solvents in its production.
• SierraSil is suitable for those mindful of radius sourcing, as it is one of the few joint health products
entirely sourced and produced in North America.

HOW SHOULD SIERRASIL® JOINT FORMULA 14™ BE TAKEN?
4 Keys to note:

• Take away from critical medications.
• Drink plenty of water.
• Larger people benefit from increasing dosage.
• Best results when taken away from food.

HOW LONG HAS SIERRASIL® BEEN MARKETED TO CONSUMERS?
SierraSil® has been marketed since 2004 (following years of "non-commercial" use). There have
been millions of servings of SierraSil®.

HOW DOES SIERRASIL ENSURE CONSISTENCY FROM BATCH TO BATCH?
Product consistency is an important part of Sierrasil Health Inc’s commitment to Quality.
There are 4 levels of testing that are carried out from the mining of the raw material to the
final release of the finished product.

Professional Reference Guide Frequently Asked Questions 19
Level 1 Testing: Before Sierrasil Health Inc mines the raw hydrothermal mineral complex that
is to be used in the SierraSil products, we confirm the consistency and quality of the
material by testing samples obtained from the mine. The testing includes electronic and
physical assays, and X-ray diffraction, to confirm that the mineral composition matches the
SierraSil mineral complex specifications. There is also microbial contamination testing, to
ensure the purity of the material. Only when our Mine Operations group is assured of the
quality and consistency of the sampled material by verifying that test results meet the estab-
lished specifications, will the mining commence.

Level 2 Testing: Before the raw material can be used in the manufacture of finished products,
it is milled using standardized procedures. To ensure that these specifications are met,
samples from each batch of the milled material are tested for composition, bioaccessibility,
microbial contamination, heavy metal impurities, particle size and density. The results must
meet the established specifications before the milled batches can be approved by Sierrasil
Health Inc’s Quality Assurance group for use in the finished product.

Level 3 Testing: Once the raw material is approved for use by Sierrasil Health Inc’s Quality
Assurance group, it is shipped to our GMP-certified and quality-approved contract manufac-
turers where the material is inspected and re-tested against their internal quality specifica-
tions. Upon approval by their Quality Assurance group, the material is then used to make the
SierraSil bulk products. More controls are in place during the manufacturing and packaging
processes of the bulk and finished products. Quality-approved master production instructions
are in place for the manufacture and packaging of the products and each batch of SierraSil
products are made according to these standardized instructions. This is to ensure that product
consistency is maintained from batch to batch, meeting our quality specifications and the label
claims for which they have been approved by regulatory authorities. After the bulk product is
manufactured, it is tested. Only if all results meet the specifications will the bulk product be
packaged into the final packaging.

Level 4 Testing: At the stage where the bulk product is packaged into final packaging, another
round of microbial testing is conducted to provide verification that no possible microbial
contamination occurred during the packaging process. Once this is confirmed with
satisfactory test results, the product can then be released from our manufacturers.

However, before Sierrasil Health Inc approves the product for sale to the public, our Quality
Assurance Group reviews all documentation from the manufacturers and confirms that all
required testing has been completed and no issues arose during the manufacture and pack-
aging of the products. With the satisfaction that the finished products are made to the estab-
lished procedures and meet all of Sierrasil Health Inc’s quality standards, SierraSil Health
Inc’s
Quality Assurance will approve the finished product batch to be made available for sale.

Professional Reference Guide Frequently Asked Questions 20
IS OR CAN SIERRASIL BE EXPOSED TO UNDESIRABLE SOLVENTS, PESTICIDES OR
OTHER UNINTENDED INGREDIENTS FROM SOURCE TO FINISHED PRODUCT?

There are no pesticides, fertilizers or solvents used in the production of SierraSil.

SierraSil is mined in a remote area a substantial distance away from industrial or agricultur-
al activity and free from any airborne or ground sourced pollutants. SierraSil is then mined,
handled and processed with operational procedures to keep it clean and pure. SierraSil is thor-
oughly tested and third party verified.

WHAT OTHER CLINICAL STUDIES IN SIERRASIL HEALTH INC. UNDERTAKING?

SierraSil has recently entered into a 24 month research agreement with UBC Food Sciences
department. The next phase of research will include mechanism of action research to better
understand the bioaccesibility of the minerals, how SierraSil passes through the digestive sys-
tem, how it interacts with other medications and supplements and some preliminary research
on how SierraSil affects inflammation of the digestive tract.

It is known that SierraSil can inhibit joint inflammation, however, there is no current infor-
mation on its effectiveness to inhibit intestinal inflammation. We have a number of customers
who have reported better digestion and relief from IBS and Chrohn's symptoms and we look
forward to learning more about this through what's known as an in vitro inflamed intestinal
cell model to investigate the effectiveness.

The bioaccesibility and drug interaction component of the research are to further understand
the pharmacokinetics of SierraSil. We know through previous research that SierraSil is ab-
solutely safe for long term use and this research will further add to that. We currently advise
customers to take SierraSil away from medication because of the detoxifying properties of
SierraSil, and with an abundance of caution advise that 4 hours should be allowed both before
and after taking SierraSil. The research will help clarify if the 4 hour window is necessary and
will help us better understand the chelating effect of the mineral. The method used is known
as Caco-2 monolayer to investigate the effects of SierraSil on the bioavailability of drugs and
natural health products.

We couldn’t have done it without our loyal
customers. Thank you for your trust and
ongoing support, we’re grateful for the
opportunity to serve you. We want to make a
difference in the lives of Canadians and always
welcome your feedback.

DIETARY MINERAL ANALYSIS OF SIERRASIL

Dietary Mineral Analysis of Sierrasil
Advanced mineralogical analysis techniques are required to accurately analyze and identify the naturally-occurring blend of silicate minerals
in Sierrasil. Conventional analysis techniques are also used to determine the typical elemental composition (see 'Total Content', below). In
addition, bioaccessibility testing is conducted to determine the amount of each element which leaves the silicate backbone and becomes
available for uptake by the body (see 'Bioaccessible Content', below).

Notes
- Recommended daily dose is 2g/day for a 70kg adult.
- The bioaccessible portion represents the amount made accessible to the body during digestion, as determined in testing that simulates the human GI tract.
- The bioavailable portion, being the portion that enters the bloodstream and is available to the tissues, cannot exceed the bioaccessible portion.
- Results presented above are typical values. Actual results may vary with test method/apparatus and product batch, among other factors.
- The above bioaccessibility results were obtained using internationally recognized facilities and procedures, including US Pharmacopeia and BARGE
(Bioavailability Research Group Europe) methods.

People and animals alike have used natural earth minerals for numerous medicinal and
health-promoting applications throughout history. Minerals in the form of clays and soils
have been consumed orally, called geophagy, as well as topically for medicinal and cosmetic
purposes. Although at first glance this behavior seems perplexing, science has revealed
several possible theories behind this practice. The theory behind geophagy, the deliberate
consumption of non-food earth substances such as edible clays, soils and chalk, is multifaceted
and relates to health functions such as mineral supplementation, gastrointestinal protective
effects and detoxification functions.

MINERAL SUPPLEMENTATION
One explanation for geophagy in animals and humans is to help alleviate nutrient deficiencies
in susceptible populations. Clay substances contain essential minerals such as calcium,
copper, iron, magnesium and zinc and potassium and phosphorus. The majority of the
studies examining the mineral supplementation benefits of clays are based on clays consumed
in Africa, most notably by women who purchase mineral-rich clays in markets to prevent
nutrient deficiency during pregnancy. Consumed regularly, these clays are thought to function
similar to a manufactured mineral supplement in industrialized societies. Another example
of geophagy is in China where clay is used as a source of minerals to replace body mineral loss
that occurs in early starvation. In addition to the repletion of body mineral content, in this case
geophagy also assists in the maintenance of fluid and electrolyte balance (homeostasis), thus
preventing body fluid losses and reducing the physical stress of fasting on the body.

DETOXIFICATION AS A FUNCTION OF GEOPHAGY
Detoxification is another commonly accepted explanation of geophagy. Ecological research
suggests that the practice of geophagy in animals serves to absorb toxins commonly found
in their food supply, such as alkaloids, tannins, oxalates, and other toxic plant constituents.
Case studies on certain cultural groups, such as the Pomo Indians of California and natives
of Sardinia, further support the detoxification function of geophagic behavior. These native
societies use clays in the preparation of certain foods with high toxin levels, for example
acorn breads. Acorns are very high in tannins, which are toxic, bitter compounds found
throughout nature. In both cultures, clays are used as an ingredient in acorn breads to help
bind harmful tannins as well as reduce bitterness. Another case study demonstrating the
detoxification function of clay is the traditional consumption of clays with certain bitter and
toxic types of potatoes in North and South America to bind toxic glycoalkaloid compounds.

Professional Reference Guide Articles 40
ADSORPTIVE AND ABSORPTIVE PROPERTIES OF CLAYS
The gastroprotective and detoxifying effects of clay minerals are directly related to their highly
absorptive and adsorptive properties. This sorptive characteristic of clays is believed to be the
basis of the majority of the health benefits associated with geophagy. Absorption is the process
by which a substance in one state is incorporated into another substance in another state, for
example liquid water being absorbed into ice. Adsorption occurs when ions and molecules bind
to the surface of another substance via physical or chemical bonds.

Toxins in the form of minerals (ie. heavy metals), natural organic toxins (such as aflatoxin)
or microorganisms such as bacteria, yeast or viruses, are adsorbed and absorbed into the
clay mineral matrix as it passes through the digestive tract. By virtue of electrical attraction,
positively charged toxins bind to the negatively charged inner and outer surfaces of the clay,
and are safely removed from the body along with the clay. A report by the Canadian Journal
of Microbiology shows that clay can absorb harmful viruses, aflatoxin, pesticides and
herbicides including Paraquat and Roundup. Motmorillonite clay is one of the only types of
clays that have both the absorption and adsorption functions. Due to these sorbent properties,
clay substances are also effective as gastrointestinal protectors in medicine as they adhere to
the gastric and intestinal mucous membrane and protect against invading toxins.

The absorptive properties of clay also allow them to be useful medicinally both as osmotic
oral laxatives and antidiarrheal agents. The antidiarrheal effect of clays is attributed to its
sorptive behavior, as absorbent minerals in clays are effective in binding and eliminating
excess water and gases from the digestive tract. Smectites and kaolinite are the major
antidiarrheal minerals due to their high capacity for water absorption. Sodium smectite
minerals in clays act by osmosis, drawing water from the blood plasma through the bowel
wall to re-establish osmotic balance to produce a laxative effect. The degree of laxative effect is
directly related to the sodium content of the clay, which produces an increase in osmotic pres-
sure in the intestine.

The sorbtive properties of clays are not limited to the gastrointestinal tract. Clays are also
used in dermatological protective preparations due to their ability to absorb skin secretions
such as greases, toxins and bacteria thus eliciting a gentle antiseptic action. The effectiveness
of clay preparations on inflammatory conditions such as acne, boils and ulcers due to the
sorption of negative inflammatory stimuli is well documented in pharmaceutical and
cosmetic preparations.

SIERRASIL ® JOINT FORMULA14 TM

The clinical and anecdotal results with regard to osteoarthritis symptoms experienced by
SierraSil® Joint Formula14™ users are mainly attributed to the noted absorptive capacity of
clays. Bioaccessibility testing on SierraSil® Joint Formula14™ confirm that only minute
quantities of the minerals in SierraSil® Joint Formula14™ are made available by the body
for absorption. The remaining minerals pass inertly through the digestive tract in the clay
matrix, binding inflammatory toxins during transit and allowing for their safe elimination
from the body and elicit a net anti-inflammatory effect. Research is underway to determine
further clinical applications for SierraSil® Joint Formula14™ based on historical uses of clays as
well as reported anecdotal benefits.

SierraSil® is a pure, 100% natural mineral composite containing a wide array of macro
and trace minerals in a rich clay structure, used to make SierraSil® Joint Formula14™. The
constituent minerals in SierraSil® Joint Formula14™ have been subjected to bioaccessibility
testing to determine the quantities available by the body for absorption upon consumption.
This testing was performed with the intent of further elucidating the mechanisms of action
of the therapeutic effects of SierraSil® Joint Formula14™, as well as to confirm that all levels
of constituent minerals fall within regulatory intake limits. The following attempts to clarify
the misconceptions regarding the presence of these minerals in SierraSil® Joint Formula14™,
and provides contextual information regarding the undesirable mineral constituents and their
presence in commonly consumed foods.

ESSENTIAL MINERALS
The essential dietary minerals are divided into two basic categories; macrominerals and
microminerals (or trace elements). Macrominerals such as calcium, potassium, sulfur,
magnesium, sodium and phosphorus make up approximately 4% of total human body weight,
and serve as structural components as well as help regulate osmotic pressure and acid-base
balance. The required intake of each of the essential macrominerals is greater than 100 milli-
grams per day, and can range up to grams per day (ie. calcium), whereas trace elements are re-
quired in amounts less than 100 milligrams per day, often much less (ie. microgram amounts).
Trace elements are essential components of metabolic constituents such as
enzymes, hormones, vitamins and biological catalysts. Deficiency in any one of the essential
minerals can lead to serious health consequences, including death. However, some of these
minerals are toxic at higher concentrations and have prompted the development of tolerable
upper intake levels for minerals.

SierraSil® Joint Formula14™ contains a wide array of minerals essential to health as well as
some which have known toxicity issues. When examining the mineral content of SierraSil®
Joint Formula14™, it is important to consider that only minute quantities of each constituent
mineral are actually released into the body upon ingestion, as shown by repeated bioaccessibility
testing. These quantities of minerals are insignificant in relation to both the required intake
levels of the essential minerals in SierraSil® Joint Formula14™, as well as regulatory limits
for minerals with toxicity issues. Thus, although it contains a wide spectrum of essential
minerals, SierraSil® Joint Formula14™ can not be considered a significant source of dietary
minerals as the majority of the minerals in SierraSil® Joint Formula14™ remain in the clay
matrix and pass through the body unabsorbed. This analysis also suggests that the mineral
content of SierraSil® Joint Formula14™ does not contribute greatly to the overall therapeutic
effects, and instead the minerals work synergistically together with the clay component of
SierraSil® Joint Formula14™ to elicit the observed therapeutic effects.

Professional Reference Guide Articles 42
UNDESIRABLE MINERALS
Although SierraSil® Joint Formula14™ contains some potentially undesirable minerals, it
is important to understand that these minerals exist in similar or higher levels in the
environment and common foods. Bioaccessibility testing confirms that the quantities of
these minerals in SierraSil® Joint Formula14™ are insignificant and fall far below established
toxicity limits. Some examples of potentially harmful minerals contained within SierraSil®
Joint Formula14™ include aluminum as well as heavy metal contaminants arsenic, lead,
mercury and cadmium. To put some perspective on the amounts of these detrimental
minerals in SierraSil® Joint Formula14™, consider the following examples of these minerals
in commonly consumed foods.

Aluminum is a ubiquitous element that is found in abundance in the environment
as well as many food products such as grain products, milk, yogurt and cheeses as well
as processed foods. An average daily dosage of SierraSil® Joint Formula14™ provides 6 mg
aluminum that is available for absorption by the body, which falls far below the regulatory
upper tolerable intake limit of 70 mg per day. In contrast, a single slice of individually wrapped
processed cheese can contain up to 50 mg aluminum, and a slice of cake or bread made with
baking powder may contain 5–15 mg aluminum. The health concerns with aluminum mostly
spring from its association with the formation of plaques in patients with Alzheimer’s disease,
as well as its health risks in people with impaired kidney function. To date, no causative link
between aluminum and Alzheimer’s has been found.

Dietary arsenic represents the major source of arsenic exposure for the general population.
Arsenic exists in many forms with varying reactivity in our environment. Pentavalent and
trivalent inorganic arsenic react with biological compounds in the body, and can result in
enzyme inactivation, structural damage and disruption of DNA synthesis. In contrast,
organic arsenic compounds are considered to be less toxic or nontoxic compared to their
inorganic counterparts. Organic arsenic compounds are commonly found in fish at levels
between 1 and 10 mg/kg, and in higher levels in seafoods (at or above 100 mg/kg). Despite
the seemingly high quantity of arsenic found in these foods, there have been no reports of
ill effects among ethnic populations consuming large quantities of organic arsenic containing
fish. The bioaccessible arsenic content of an average daily dosage of SierraSil® Joint
Formula14™, 0.0007 mg/day, falls far below the amount commonly found in fish and
seafood as well as the established upper intake limit of 0.15 mg/day, and thus not be
considered a safety concern with SierraSil® Joint Formula14™.

Crude mineral analysis shows that SierraSil® Joint Formula14™ also contains minute
quantities of other potentially undesirable minerals- these include mercury, cadmium and
lead. However, as with arsenic, bioaccessibility testing shows that these minerals are also
present in much lower quantities in SierraSil® Joint Formula14™ than many commonly
consumed foods and thus do not present safety concerns.

Like arsenic, mercury is also found in fish and shellfish largely in the form of methylmercury,
which is recognized as more toxic than inorganic mercury. Mercury targets the nervous
system, particularly the developing brain as methylmercury is able to pass through the

Professional Reference Guide Articles 43
placenta about 10 times more readily than other mercury compounds. The concentration
of methylmercury in most fish is less than 0.4 mg/kg, however predatory species such as
swordfish and shark may contain up to several mg/kg. The average daily intake of
methylmercury ranges from 0.2 to 3–4 mcg/kg body weight/day, which is dependant on
fish and seafood intake. In contrast, bioaccessible mercury in SierraSil® Joint Formula14™
is present in nil amounts in an average daily dosage, well below the upper intake limit of
0.05 mg/day, and thus also does not represent a safety risk.

Diet and drinking water are the main routes of human exposure to cadmium and lead. The
highest concentration of cadmium in foods are found in mollusks, kidney, liver, cereals, cocoa
and leafy vegetables. In addition to foods and drinking water, lead-containing manufactured
products and air contamination also contribute significantly to lead intake. Infants and
children are at the highest risk of lead exposure as they absorb lead from the diet with greater
efficiency than adults. As with other potentially undesirable minerals in SierraSil® Joint
Formula14™, cadmium and lead levels in SierraSil® Joint Formula14™ do not reach
significance as their concentrations are over 100-fold below established upper intake limits.

MORE THAN ITS MINERAL COMPONENTS
From this data, it is apparent that the bioaccessible amounts of both the health-promoting
and potentially toxic minerals in SierraSil® Joint Formula14™ are very low based on tolerable
upper intake limits and levels commonly found in foods and the environment, and thus do
not represent safety concerns. Compounded with the numerous other toxicity studies showing
SierraSil® Joint Formula14™ to be non-toxic and safe for human consumption under the
recommended conditions of use, the information here serves to provide further support
to the safety of SierraSil® Joint Formula14™ as a natural joint health product.

SierraSil makes a difference, no question about it.

DAMON ALLEN, 2005 CFL M.V.P AND M.V.P OF THE 2004 GREY CUP | TORONTO, ON:
In 2007 I received a product called SierraSil Joint Formula and a Topical Spray for Pain Relief.
The game of football is a violent sport and there are times when sore muscles, aches and
pains come from playing a hard fought game. I have been playing in the CFL for 23 years as
Quarterback, so I know about aches and pains. When I turned 40, after games it would take
me much longer to recover from a game than in the past. So I started taking SierraSil and after
about a week, I noticed from workouts, practicing and games that my soreness and aches and
even at times my back pain was subsiding. I started telling my teammates and they started
taking the product out of my locker, they really liked the topical spray. So what am I telling
you? The product is great!! I’m 44 years old, in my off season still taking SierraSil, I’m training
and my body feels great. (Mr. Allen subsequently retired from professional football).

ANTHONY TOTH, PROFESSIONAL TRIATHLETE | VANCOUVER, BC: I’m a professional Triathlete and 5

CHERYL BERNARD, 2010 OLYMPIC SILVER MEDALIST IN CURLING | CALGARY AB: I was self medicating
with Ibuprofen for a knee injury that I had from too much training when I discovered
SierraSil. My doctor said that the cartilage and my IT band above and below the knee where
inflamed from too much exercise, and even seeing him 6 times a week wasn’t getting rid of the
problem. Within a month of using SierraSil I noticed a difference with my knee and was able to
return to my full workout schedule. I also love the spray and use it every time on my knee and
calf before I curl, and in the last tournament every time before I threw!

JULIA MURRAY, OLYMPIC SKIER | WHISTLER, BC: Since the 2010 Olympics, I have had two ACL

and stenosis that every move was a concentrated effort. Fatigue was a constant presence. My
daughter-in-law who works at Health Food Heaven in Squamish BC is very knowledgeable
and her choice of treatment for me was SierraSil. After only a few days on these capsules, the
improvement was amazing. I can move about without a walker, wheelchair or cane. I have
much more energy and endurance and sleep at night is the best in years. When I leave Canada
it will be with an ample supply of SierraSil in my bags. In returning home to Ohio, I hope to
introduce my doctor to this miraculous product that may benefit others with similar conditions
and I indeed, may be able to fulfill my Doctor's hope to be her first centurion patient, with the
help of SierraSil.

BRIAN FLETCHER | DUNCAN, B.C: I have been taking SierraSil now for 1 month after hearing
about it on the Shell Busey radio program. I have had bad knees for years, owing it to Gout. My
doctor recommended that I should have knee replacements but after taking SierraSil I have
decided not to, as I do not have any pain whatsoever. I take 3 capsules everyday and they work
just great for me.

IRENE MCMILLIAN | WINDSOR, ON: After suffering from Rheumatoid Arthritis and Osteoarthritis
for 19 years, I was introduced to SierraSil Joint Formula14™. After 4–5 days I no longer needed
my cane to get me started in the morning. As for my walker, it is also collecting dust. I can go
shopping for 2–3 hours and stand for long periods of time, something I could not do before
using SierraSil.

AUDREY PURCHASE | GIROUX, MANITOBA: Hi, wanted to let you know before I started SierraSil
I inquired with my doctor. He told me it would take 3-4 months to help. I am suffering from
fibromyalgia and arthritis which affects the muscle and joint. After 2 and half months, I
could hold my neck with no pressure; I take three capsules daily and will continue, they are
“helping a lot”. No one can expect miracles over night. Thanks again for giving me relief.

GENEVIEVE LEIS | PUEBLO, TX: Iam 80 years old, and I am so delighted with SierraSil. In a very
short time it has done more to eliminate the toxins and inflammation in my stiff out-of-align-
ment spine and helped my overall flexibility and ligaments more than my other supplements
and therapies in 30 years. And I am gaining strength and hopefully this is going to save me
from having to go to a nursing home.

RICHARD MARTIN | TORONTO, ON: I am a retired business owner of 64 yrs of age and I have been
doing triathlons for about 20 years. A friend recommended SierraSil in April of 2008, as I
mentioned that my knees were shot and I may have to give up running altogether. After 2–3
weeks of use I could feel that my usual pain in my knees wasn’t as bad as before, and after 2–3
months I ran pain free for the first time in years. I can now get up in the morning pain free
even after a 2 hour run and a 4 hour bike ride the day before. I have recommended your prod-
uct to at least a dozen friends, and have nothing but glowing reports back. It’s wonderful!

DARRYL PENNY | ALTAMONT, MB: 3 years ago I was having great difficulty walking due to pain.
I took stairs sideways 1 at a time. My partner told me about SierraSil and suggested I try it. I
thought oh yeah spend money on some junk pill. I agreed to try it for 2 months. 4–6 weeks
into taking these I ran down stairs and back up again. I didn’t believe my partner when she
told me what I had just done. I have been faithfully taking it since and can still outrun my chil-
dren as well as my neighbor’s children. Nice to be able to work all day and not be stiff or sore.
Thank you SierraSil.

CHUCK RALLISON | RIMBEY, AB: I play senior men’s softball in Alberta and each fall I also play
in Utah, USA. My knees were a major deterrent to running. I started taking SierraSil about 6
months ago and have much less discomfort while playing ball and the next day. I also notice
less trouble with my Crohn’s condition.

FRANK KELLY | VANCOUVER, BC: Some years ago I began to experience throbbing pain in my right
knee, my doctor diagnosed Osteoarthritis. I endured the painful condition for approximately 1
year. Then I discovered SierraSil and my condition improved within 2 weeks. The only change
in my lifestyle has been a small increase in my intake of Vitamin D and I think more signifi-
cantly my daily dosage of SierraSil. I have no hesitation (and have done so) in recommending
SierraSil to all my acquaintances who complain of joint pain or stiffness.

DEB SMITH | KINDERSLEY, SK: I heard about SierraSil through a friend from B.C. when I was
battling chronic pain from a herniated disc in my back. Within weeks of taking SierraSil
daily the pain almost disappeared – I could hardly believe the instant relief I got. I tried
everything from meds to chiropractors to physio to a cortisone injection and nothing worked
until SierraSil!

REID STEKEL | NORTH YORK, ON: Following my back surgery a couple of years ago, my wife read
an article about SierraSil. Being a natural mineral, I decided that no harm could be done so I
tried it. Within a month, pain levels decreased (so did my intake of prescription meds) and I
was waking up with dramatically less stiffness. After running out of SierraSil, I decided to see
what would happen to me if I didn’t take it. Within a week I was miserable! I have been happily
popping my 3 capsules ever since. Thank you SierraSil!

GORD MUDIE | HANNON, ON: After suffering severe constant pain in my hands, biceps and
shoulders due to a carpal tunnel syndrome since Nov-09, my wife heard about SierraSil and
picked up a bottle plus the spray. I tried another advertised meds plus medical visits which did
nothing. After 3 weeks the pain in shoulders, biceps and arms was gone and the hands are
80% better. Thanks to SierraSil!

KATHY BURTON | SURREY, BC: I just wanted to share how happy I am with SierraSil for my knee.
My knee was so stiff I could barely walk up and down stairs. I had to stop walking my daily
1km walk as there were too many hills, I could manage only flat areas. After taking SierraSil
for 4 days I noticed an improvement. I have been taking SierraSil for 4 months. I have had a
great summer, walking anywhere and cycling for up to 40km trips. I have recommended this
product to many others and they have the same amazing results!

ARDELL PAUL | LONDON, ON: Marvelous product! I’ve had fibromyalgia for 20 years and muscle
pain is greatly reduced. Arthritic joints are much more flexible.

DOUG AND JOCELYN CORBETT | WINFIELD, BC: It is with pleasure that my wife and I would like to
add our names to the list of satisfied customers of SierraSil Joint Formula14™. We have found
great relief to knee and leg pains, after using for a short period.

ERNIE WALL | LAC DU BONNET: I
had replacement hip surgery 3 1/2 years ago and the Dr. said I
would need my knee done as well. I started SierraSil and now don’t need the knee surgery at
this time.

JIM DOAN | KAMLOOPS, BC: I have been teaching karate for almost 30 years and I have had chron-
ic hip pain for even longer before using SierraSil. I would not be able to walk or drive long
distances without developing a painful limp. It has now been 10 months without a limp. This
includes a six hour flight to Hawaii and plenty of walking once we arrived. I never hesitate to
recommend SierraSil to my students – I am convinced!

LEESA NACHT | STOUFFVILLE, ON: Over the last year it felt like every workout made me ache more
and more. At 54, I thought being fit should make me feel better not worse. Today is only day 11
on SierraSil and I can’t believe the change. No more aches and pains! I am even sleeping better
and wake up without any stiffness! Thank you for improving my quality of life.

LORRAINE SAUVE | ST. GEORGES, MB: Clark, our 6 year old dog, was having problems with his
hips and left hind leg. He walked on 3 legs & used the other for balance. When lying down
he struggled to get up. I decided to give him SierraSil. He received one daily & one aspirin; it
helped. While checking on-line it said 1 capsule for 44lbs of dog. He now gets 2 capsules & no
aspirin. He’s happy and extremely active, thank you SierraSil.

MERLE HILL/WINNIPEG, MB: After 3 days of taking SierraSil I was free of pain in my knees and
back and still free of pain – great product – and gave me back lots of energy. Thank you!

Thank you for your input on the Mary Pack Arthritis Program (MPAP) Provincial Arthritis Strategy. There
are about 700,000 British Columbians with osteoarthritis and 100,000 with rheumatoid arthritis and other
inflammatory arthritides. These numbers are expected to grow significantly over the next twenty years.
Our objective at the MPAP is to better serve this growing population using existing resources. I strongly
believe that, using a provincial technology platform, earlier intervention including education healthy diet,
exercise, weight management and life style, including sleep, will reduce the impact of osteoarthritis and
rheumatoid arthritis. In addition, natural health products may play a helpful role in improved patient
outcomes and reduced costs.

About two years ago, after discussion with other physicians, I investigated the research on the SierraSil®
minerals. Subsequently I recommended them to some of my patients with mild to moderate OA and/or
RA. It is my observational experience, that the minerals have been helpful in the majority of patients.
Many of these patients have felt less pain and have been more able to resume exercise or enhance their
mobility or other activity, improving outcomes and well-being. I note that the onset of such results has
typically been within one or two weeks surpassing my expectations. As these are just my observational
findings, may I encourage SierraSil Health to continue its research including: Additional mechanism of
action investigation; assessing potential medication interactions if dosage is not separated from such
medication; and conducting additional clinical studies as resources permit.

Again, thank you for your helpful input to the MPAP, and continued good wishes with your Company
mission to help people be healthier and more active.
